Match Start Position

Match Start Position is useful in defining specific portions of a symbol for comparison. For
example, if a symbol contains a part number, manufacturing date, and lot code info, but only the
part number information is needed, set the imager to sort only the part number and to
ignore the other characters.
Match Start Position determines the portions of symbols that will be matched by defining
the first character in the symbol (from left to right) that will be compared with those of the
master symbol, when
For example, if Match Start Position is set to 3, the first 2 characters read in the symbol
will be ignored and only the 3rd and subsequent characters to the right will be compared,
up to the number of characters specified by Match Length.

will disable this feature.
